Abstract

One of the villages in Bali that is still running its daily life traditionally is Tenganan Pegringsingan village. This village is located in Manggis District, Karangasem Regency, Bali Province. This village is a Bali Age village (original Balinese village). This village has three hills, namely Kangin Hill, Kauh Hill, and Kaja Hill. The condition of the forest is very sustainable, because it is managed traditionally. There are various plant species in it, some are used traditionally and there are some plant species that have not been used traditionally. In the meantime, there has been no research that has recorded the plant species in the forest, both those that can be used by the local community and those that have not been utilized. This study were to determine the composition of useful plant species in the forest of Tenganan Pegringsingan village, Bali. and to determine the diversity index of useful plant species in the forest of Tenganan Pegringsingan village. This study was an explorative study. The population of this study was the entire useful plant species in the area of Bukit Kangin forest. The sample of this study was the entire useful plant species covered by the squares sized of 20x20m (for data collection of mature habitus species), 10x10m (for sapling), and 1x1m (for seedling), 65 squares for each data collection. The plant species composition analyzed descriptively and diversity index refers to Shannon-Wiener. Then, it followed by the analysis of equity (E) and species richness (R). The results of the study showed that (1) there were 77 plant species in Bukit Kangin forest. Based on the Tenganan Pegringsingan Bali Aga social culture, 46 of them (60%) were useful plant species for the local people, whereas the remaining 31 plant species (40%) were the unutilized plant species, (2) There were 31 plant families which consisted of 46 useful plant species with as many as 2,249 total species individual. The conclusion of this research is the majority (60%) of these plants is used by the local community and 40% are not traditionally used by the local community. Useful plants traditionally utilized by local communities are for the purposes of religious ceremonial material (Hindu) as many as 29 plant species (35.80%), for medicinal purposes as many as 18 plant species (27.70%), as many as 17 plant species food ( 20.99%), the need for board materials is 13 plant species (16.05%), the need for clothing and industrial materials is 2 plant species (2.47%).

Abstract

Phalaenopsis amabilis (L.) Blume or moon orchid is a type of orchid that has high economic and aesthetic value, but the flowering time is relatively long. Induction of flowering was carried out by inserting the PaFT gene with the ubiquitin promoter in the plant to obtain transgenic candidate plants (transformants). Transformant plants were grown in New Phalaenopsis (NP) medium for 40 weeks. Molecular analysis on transformant plants obtained P. amabilis transgenic. Amplification with ubiquitin (forward) and T-Nos (reverse) and deg PaFT primers in transgenic plants obtained DNA sequences of 1137 bp and 533 bp, while for non-transformant plants with deg PaFT primers, DNA bands of 1500 bp were obtained. The development of transgenic and non-transformant plants were then compared at 10, 20, 30, and 40 weeks of age. The results showed that transgenic plants produced multiple shoots/multishoots and longer roots compared to the roots of non-transformant plants. According to the literature study, there are morphological differences in some plants that carry the flowering locus T gene compared to nontransforman/wildtype plants.

Abstract

Sardinella lemuru, one of the important pelagic fish in Bali Strait waters, has been reported to be in the overfishing condition. Various studies have been conducted to understand its population condition. Length-weight data has been also widely used to understand the population dynamic of S. lemuru, although data collection generally using manual direct measurement methods, which has the disadvantages if used on the enormous number of samples. Therefore, this research aims to understand the significance of S. lemuru length measurement using digital image analysis (ImageJ) compared with the manual measurement. Moreover, this research also aims to understand the population condition of S. lemuru landed in PPI Kedonganan analyzed using its length-weight data. The result indicated no significance difference between length measurement using manual methods and digital image methods, thus conclude that digital image data can be used to measure the fish length and represent the accurate measurement. Population condition analysis showed that S. lemuru population is in isometric condition (b=3); with indication of declining in the length growth pattern compared with previous research (L∞= 20.75 cm with K= 1.1); the mortality estimation showed that fishing mortality (F=1.27) was lower than natural mortality (M=2.22), with the survival rate higher on smaller size fish. This research result can be used as an addition to the S. lemuru fisheries data and can also be used as reference methods to help conduct sampling and data collection more efficiently.
